The R740xd is the storage-dense variant of the R740 — same 14th-Gen platform, reworked chassis that trades expansion for up to 32 drive bays.

Software-defined storage, backup targets, object storage nodes, hyperconverged builds.
| CPU support | Intel Xeon Scalable 1st/2nd Gen, 2 sockets |
|---|---|
| Memory platform | Identical to R740: 24 × DDR4, 2666/2933 by CPU generation |
| Drives & RAID | Up to 24 × 2.5" front + 4 mid + 4 rear (variant-dependent) · 12 × 3.5" variants |
| PCIe & accelerators | Fewer usable slots than R740 depending on rear-bay configuration |
| Power & networking | Dual PSU up to 2000W |
Same rules as R740. For storage nodes, capacity per DIMM often matters more than peak speed — a 32GB×24 build is the common sweet spot.
vs R740: choose xd only if you need the bays — it costs PCIe room. vs 15G R750: newer platform, but used xd units are the value play for bulk storage.
This platform takes the 32GB DDR4 ECC RDIMMs we regularly source and quote — see part numbers & availability, or ask for a free compatibility check with your RFQ.
